He felt that this place should be a ruin, or the cave mansion of some powerful being, but who had created this cave mansion?
And what was this ruin all about?
Why did this cave mansion change when he entered?
Everything was too unusual.
"What is inside here?"
Zhou Yan pondered in his heart, a premonition that if he left this place, something extraordinary might happen.
Just then, a thought came from his mind.
This thought was sent by the shadowy figure within the black mist vortex.
"Kid, you are quite lucky to have the honor of becoming my nourishment."
"However, if you want to enter this cave mansion, you must pass a test."
"As long as you can pass the test, you can become my newly accepted disciple."
"As for the treasure you mentioned, it's not too late to give it to you after you pass the test."
The shadowy figure in the black mist said faintly, his words carrying an unquestionable authority.
Upon hearing this, Zhou Yan immediately understood that this cave mansion was likely his fortune.
He finally understood that this cave mansion was a trial set for him.
"A test? Are the rules of this cave mansion different from the outside?"
Zhou Yan thought to himself, but at this moment, he could not afford to worry about that.
He knew he had to pass the test as soon as possible.
With that, he began to walk forward following the instructions of the shadowy figure.
He found that with every distance he moved forward, the power grew stronger, and sometimes it was accompanied by a sense of danger.
However, he gritted his teeth and persisted, refusing to retreat.
During this time, he encountered many demonic beasts and monsters, but they were all swallowed by the black mist.
"Bang!"
Finally, he reached the black vortex and punched towards the center of the vortex.
"Bang!"
A dull sound reverberated, and a crack was blasted open in the center of the black vortex by a force.
At this moment, Zhou Yan's figure rushed out.
He saw that in the space in the center of the black mist vortex, a palm-sized stone was floating, and this stone was a green fruit.
"Is this the legendary spiritual medicine? It's exactly the same as the ones outside!"
Zhou Yan's eyes narrowed slightly, and he secretly said to himself.
"Rumble!"
Suddenly, a vast oppressive force surged from the void.
Zhou Yan's body trembled violently, and his face turned slightly pale.
He realized that the terrifying oppressive force seemed to be testing his strength.
"I want to see how strong this thing is!"
Zhou Yan snorted coldly, waved his arm, and reached for the green fruit.
As soon as his hand touched the green fruit, the terrifying oppressive force disappeared instantly, allowing Zhou Yan to easily grasp the green fruit.
"This is?"
Zhou Yan's pupils suddenly contracted, and a look of intense disbelief appeared on his face.
Because he discovered that this green fruit contained an incredibly powerful vitality.
This green fruit seemed to contain immense power, making him feel comfortable all over just by being near it.
However, he also knew that this power was definitely a good thing.
But he had no way to swallow it directly.
Because he knew that if he swallowed the fruit, it would surely explode.
At that time, not only would his physical body be destroyed, but even his Nascent Soul would suffer severe damage.
"What is this? Why is it so strange?"
"Also, what kind of heavenly treasure is this? I've never seen anything like it."
Zhou Yan's heart was filled with doubt, his emotions complex and unable to calm down.
"Forget it, since I'm here, I won't dwell on these things."
"I'll take this green fruit first, hoping it can help me break through my limitations and reach the true Martial Emperor realm."
Zhou Yan thought to himself, and then, without hesitation, he swallowed the green fruit.
As the green fruit was swallowed, a green radiance instantly enveloped him, and then he felt his entire body boiling.
At this moment, his blood, bones, and veins were all being transformed by the power of the green fruit.
This feeling was incredibly refreshing.
"Boom boom!"
And his body was improving at a terrifying speed.
"This is..."
Zhou Yan's face was filled with shock. He discovered that with the help of this power, the meridians in his body were undergoing metamorphosis at an astonishing speed, and with each metamorphosis, his cultivation would increase.
Soon, he advanced from the peak of the second stage of Martial King to the early stage of the fourth stage of Martial King.
This scene was almost unbelievable for Zhou Yan.
Although he knew that the green fruit contained incredible power, he never expected it to be so astonishing.
This transformation caused Zhou Yan's strength to increase by more than several times, making him feel as if he had surpassed the peerless geniuses in the True Martial Sacred Land.
However, Zhou Yan knew that he was far from his optimal state.
This green fruit might be a good thing for others, but its effect on him was not significant.
After all, the divine power within him was obtained from the "Chaos Art" and was not cultivated through hardship.
"It seems I can only rely on myself."
Zhou Yan's eyes flickered, and his mental power circulated wildly, spreading outwards.
He wanted to see if there were any mechanisms or traps here that could harm him.
However, this space was very quiet, and apart from the vast oppressive force and the terrifying suction, there was nothing unusual.
"No traps, this should be an independent world."
"Yes, this should be the center of our space."
"And this should be the legendary mysterious forbidden area!"
Zhou Yan thought to himself.
Although he did not know if there were any other powerful beings in this mysterious space, he was certain that their current situation was quite dangerous.
He had to leave this place as soon as possible.
With that thought, Zhou Yan moved and flew towards the direction from which the suction was coming.
"Whoosh!"
After he had flown for thousands of meters, the terrifying suction suddenly intensified, causing his body to involuntarily stop.
"What's going on? Does this force want me to stay here?"
A look of confusion appeared on Zhou Yan's face.
However, he did not stop and continued to advance.
But the moment he advanced, the suction suddenly increased several times.
"Not good! This suction is going to drag me into this area, isn't it?"
